Engine Performance problem
2003 Toyota Corolla 4 cyl Front Wheel Drive

The engine stutters at starting(especially when it is cold) but this stops after about 30 seconds. If I move immediately after starting it does not respond to the accelerator stuttering for a few seconds before responding. The problem disappears when the engine warms up. I have changed the plugs and the fuel pump but the problem persists.
Thanks for your attention
